Robin Thicke, along with Pharrell Williams and T.I. are suing the family of late singer Marvin Gaye after they claimed that their hit single Blurred Lines bares a strong resemblance to Gaye’s Got to Give it up and another song, Sexy Ways by Funkadelic.

The family as well as Bridgeport music who owns Funkadelic’s music claim that Blurred Lines bares such a strong resemblance that it infringes copyright.

As a pre-emptive measure, the singers have launched their own lawsuit against them.

The lawsuit reads: “Plaintiffs, who have the utmost respect for and admiration of Marvin Gaye, Funkadelic and their musical legacies, reluctantly file this action in the face of multiple adverse claims from alleged successors in interest to those artists. Defendants continue to insist that plaintiffs’ massively successful composition, ‘Blurred Lines,’ copies ‘their’ compositions,” the suit reads.

“But there are no similarities between plaintiffs’ composition and those the claimants allege they own, other than commonplace musical elements. Plaintiffs created a hit and did it without copying anyone else’s composition.”

In an interview with GQ magazine back in June, Thicke claimed that Got to Give it up was one of his favourite songs and he later told Pharrell: “Damn, we should make something like that, something with that groove.”
